Two weeks ago we launched the new GPUPI benchmark in cooperation with Overclockers.at. The new benchmark features both CPU and GPU benchmark tests and resembles the good old SuperPI interface. The stream of new submissions followed suit and based on the feedback from the community, a new version was released three days ago.

The most important changes are of course the introduction of a 64bit and legacy version for respectively optimal performance and compatibility with older hardware configurations. We are also very pleased that GPUPI V2.1 now supports Windows 8 and up as it detects the timer used for the benchmark time-stamp. Lastly, it is now possible to save your benchmark result in a datafile and upload it later. In particular the 64bit version, in combination with Intel's latest drivers, will result in a significant performance boost. This is the reason why some community members hinted that the older version of GPUPI had better performance; an experimental v1.2 64bit beta was available.

Because the datafile offers superior security compared to a screenshot, a datafile will be MANDATORY from May 3, 2015 forward. If you have scores with GPUPI V2.0 with just a screenshot as validation proof, please submit them before this date. After May 3, no scores without the datafile will be accepted for submission. From May 3, 2015, GPUPI V2.1 will be the ONLY allowed version for submissions.

64 bit version to allow 64 bit hardware and drivers to use their full potential (GPUPI_x64.exe).

New time measurement using QPC if available and RTC as fallback for Windows 7/XP.

HWBOT submissions can now be saved as data file to disk and submitted later.

HWBOT submission supports skipping of CPU/GPU (for detection errors) and allows erroneous submissions to be updated manually when needed. Therefor the pure manual submission of scores will be disabled again, because it's the most secure way.

Legacy version compiled with Visual Studio 2012 (Update 4) and CUDA toolkit 6.0. It has CUDA and OpenCL support for Windows XP and allows GeForce 200 series cards (CUDA capability 1.3) to run the benchmark. The Legacy version is slower than the default executables and should only be used if necessary!

GPGPU using OpenCL/CUDA is a very big part of high performance computing for crunching numbers. It was about time to include something like that. And what would be better for that job than a benchmark made by an overclocker (that's me!) for overclockers that resembles SuperPi? Nothing diluted here in my opinion.

As for the "junk benchmark" you will have to elaborate on that to be taken seriously.

"Context error" sounds like an OpenCL initialization issue, which is almost always a driver thing. Try to install the newest drivers. Btw, sometimes the newest GeForce XP drivers are not listed at nvidia.com, but only available on the web.
Have you tried selecting the CUDA version for the calculation yet?

Strunkenbold said: Just want to say that this Benchmark is one of the best ever coded. Active development, fast bug fixing, seamless integration with hwbot. Very cool.

Agreed, was talking to a friend a long time ago and was saying that there needed to be a benchmark like this on the bot. Now that it's hear I'm glad to see it's doing so well, keep up the good work mat :)

Mat, can you tell me how to save a file, including the Pi calculation is done pop-up.
I can only save a screen shot when I have closed the pop-up that the Pi calculation is done.
Is it than still valid ?

_mat_ congratz for that nice benchmark. IMHO by far the best of the recently added benches last few years :)
Works flawless, light, simple and clear validation process, tweakable benchmark and so on... Keep up the good work, this is great for the community.
